SPECIFICATION forming part of Letters Patent No. 766,234, dated August 2, 1904.

Application filed March 4, 1903.

To all whom it 'may concern,.-

Be it known that I, EDWIN FIDELL, residing in Jersey City, Hudson county, and State ot' New Jersey, have invented certain new and useful improvements in Conveying' and Delivering Means for Packaging'-Machines, of which the following' is a specitication.

The subject ot' the present invention is a novel means for conveying and delivering to packaging-machines measured quantities of dry material in reduced or granular condition, the said Ineans having' for its more prominent objects increased capacity as compared with prior arrang'ements for a similar purpose, positiveness and eticiency of operation, as well as simplicity and durability of construction.

l/Vith the above and other purposes in view the novel conveying' and delivering' means comprises a peculiar arrangement of movable frame carrying a series of invertible boxes conveniently disposed so that a plurality of the same can during the movement ot' the frame have measured quantities of the material deposited therein, together with provision whereby the said boxes will be automatically inverted in regular succession as they arrive at the discharge-point.

There are other important features and details connected with the invention, which are explained at length in the subseq uent extended description. Among these Inay be noted the devices for maintaining' the boxes in a nondischarging position throughout their travel with the frame, except at the point of their discharge, said devices at the same time presenting no interference with the operations ot' depositing' the material within the boxes during' their movement with the frame.

The overhanging character of the means permits a horiZontally-rotatable box-carrier to be employed for delivering directly to the hopper of the packaging-machine, which latter can be compactly disposed relative to the novel conveying' and delivering' means by occupying' a position beneath the overhang' of said means.

In the accompanying drawings, forming' part of this specification, Figure 1 is a plan view otl a conveying' and delivering' means Serial No. 146.058. (No model.)

embodying' my invention. Fig. 2 is a vertical elevation ot' the construction disclosed in Fig. l, the hopper and a portion of a packaging-machine being' illustrated in outline. Fig'. 3 is a longitudinal sectional view of one of the boxes and certain appurtenances, the parts being illustrated on an enlarged scale. Fig'. 3 is an inner end view or' said box and appurtenances. Fig'. 4 is an enlarged detail plan view ot' one ot' the sector-shaped keepers for normally maintaining' the boxes in their nondischargingpositions. Fig'. 4Fis a cent1-allong'itudinal view of the keeper shown in Fig'. 4. Fig'. 5 is a detail view, partly in section, of parts supported by the standard. Fig. 6 is a detail view of the frietion trackway, dotted lines illustrating the position of two ot' the box-rollers thereon. Fig. 7 is an enlarged detail view illustrating' the manner of pivoting' the keepers.

Similar reference characters are employed to designate corresponding' parts throughout the several figures of the drawings where they occur.

I have represented the rotating trame and coactingl parts as being' supported in an elevated position by a standard A, mounted on a base A', lixedly secured in position, the upper portion ot' the standard overhaug'ing' and provided with a bearing n, in which is rigidly clamped the lower end ot' a vertical spindle B. Also rigidly connected with the bearing are the inner ends of two arms C and D, disposed radially with respect to each other and shown as spaced at about ninety degrees apart.

On the outer end portion of the arm C isa horizontal track-segment C', curved concentric with the axis represented by the spindle and of a length proportionately as represented in dotted and full lines, Fig'. l. rlhis section partakes of a limited yielding' cliaracter,wliich in the drawings is provided for by a spring'- seated bolt c, supporting' said trackway and adjustably secured by a nut c, engaging its lower threaded portion c2 beneath the arm C. The spring' being' expanding permits the nut c' to be manipulated to adjust the deg'ree of resistance with which the trackway is adapted to yield.

Rotatably mounted upon the spindle B im- TOO mediately above the arm D is the box-carrying frame comprising a central hub having radially-projecting sockets e, in which are rigidly engaged the inner ends ofA a corresponding number of radially-disposed rods e', connected at their outer ends to a ring E.

Revoluble with the hub of the box-carrying frame is a horizontal beveled gear-wheel E, and upon the spindle B above and independently of the wheel E is a bracket F, having a lower horizontal. portion f, providing' a bearing for the inner end of a horizontal shaft F adapted to turn therein, the outer portion of said shaft being revolubly supported in a bearing (Z, carried by the outer portion D of the arm D, vertically bent at a point Aconsiderably external to the periphery of the ring E. Secured on the shaft F is a bevel gearpinion Ffi, meshing with the wheel E'. rIhe shaft F/ proximately to the ends of the bearing has suitable means, as collars f2, for preventing end movement ot' the shaft and maintaining the pinion in properdriving relation to the gear-wheel. On the outer projecting end of the shaft is a sprocket-wheel f 3,.

designed to be driven by a pitch-chain f* from any suitable source of power.

The bracket F has at one side a small boss f5, provided with a threaded perforation for a screw f, by which said Vbracket may be rigidly clamped in position on the'stem. Radi-- ally projecting from. the opposite side of the bracket and in the direction of the point where the box discharge is to take place is a horizontal socket f7, in which is rigidly connected the inner end of an outwardly and downwardly curved rod g, supporting on its lower end an extended horizontal shoe G, curved concentric with the stem and having its ends g turned upward to a slight extent and with a moderate curvature. rlhis shoe G is located in a slighly higher plane than the upper edge of the ring E and at a point considerably within the inclosed area of the same.

A number of boxes H are arranged around the periphery of thering E andin closely'- associated relation, said boxes being radially disposed with respect to said ring and each` comprising a receptacle, the sides L, bottom t, and outer end h2 of which are disclosed as being of sheet metal, while the inner end is presented by an appropriately-shaped part L;i of a casting H. This casting integrally includes. a tubular sleeve and roller if), lrigidly thereon. r

A comparatively elongated bolt I has a disklike head e' seated against the part L of the casting, said bolt bearing loosely in the is solid, while the lower part thereof is recessed, so that said upper part will help thel receptacle to dump evenly and easily at the required time.

At regularly-spaced points on the inner side of the ring E are pairs of vertical ears l7', horizontally perforated to constitute bearings for the trunnions 7" of a circular series oi' closelyrelated keepers J, said keepers being radially arranged, as indicated more clearly in Fig. l. Each keeper comprises an outer sector-shaped body J, containing a plurality of radially-disposed and approximately rectangular openings, each of such plan dimension that it will substantially conform to the open top of one of the boxes. The body at its inner and outer sides, as well as ends, is constituted by a vertical iange f2, the body being spanned by intermediate webs f3, which form the distinct openings, the severalv iianges and webs being' rounded at their tops, as indicated by ji.

Inwardly extending from the top of the body is a shank J2, which may be of the convliguration disclosed in Figs. l and 4 and contracts toward the rear. At an intermediate point the shank has a transverse enlargement f at its lower side, adapted to snugly it be tween the ears j'and perforated for the passage of a pin Jforming the laterally-projecting trunnions j", while the inner end of the shank has an Lipper lug j, in which is located a pin f, headed Vto revolubly retain a roller jg.

1t will be noted that the rollers of the boxes are in such circular arrangement thatat one point of the rotation of the ring E they will be brought in contact with androll upon the upper face of the trackway C. Also the rollers 17'8 of the keepers are so positioned that as the ring revolves they successively Contact with one oi' the curved ends of ;the shoe Gr and are depressed to pass beneath `the same, thereby tilting' the keepers on their trunnions to raise the body portions thereof. The boxes and keepers are so mounted 1n `position that the body portion of eachfkeeper normally rests by gravity upon the upper `edges ot' the open tops oi' a` plurality or' the boxes, the openings inthe keeper coinciding with the open tops of the boxes beneath.

In practice several attendants occupying suitable positions with respect to the machine.. are engaged in depositing in each box a previously-weighed quantity of the material to be packaged.' The revolution of the box-carrying frame and continuous series of boxes thereon permits the material in distinct weighed quantities to be deposited in the sucl cessive boxes as they sweep past at a com-v paratively high rate of speed, dependent upon the character and condition of the material.

As each box is brought into proximity of the points when it is to discharge into the hopper of a packaging-machine, which hopper will be oppositely located with respect to y the trackway C and shoe G,'the roller if of IOO the box will pass upon said trackway and by .reason of the frictional eharacterof' the latter be turnedpthereby inverting' its receptacle and delivering' the contents thereof to the hopper of' the packaging-machine. The position of the shoe G is such, however, that immediately prior to the passing' of the roller /f onto the trackway, as described, the roller j" of' the keeper pertaining' to the particular sition with its open end uppermost, at which time the roller of its keeper will have passed beyond the shoe, permitting the keeper to resume its normal position upon the top of' its g'roup of' boxes and said g'roup and keeper to be moved around to a point where the boxes can ag'ain have material deposited therein.

It will be appreciated that the general construction and arrangement of the boxes, keepers, and coacting' parts are such that each box will be positively operated to deposit its contents before the similar operation of the box succeeding', so that the successive quantities ofl material can deliver with precision, notwithstanding' the considerable speed at which the box-carrier rotates. Furthermore, the conditions aforesaid increase the capacity of the apparatus considered with a given number of boxes for the rapid delivery of the weighed quantities of the material to the packag'ing'machine.

'l he novel conveying and delivering means is not only extremely simple, embodying', as it does, comparatively few parts, but is not liable to irregularity of and interference with the proper working' of the parts.

An important feature of my invention resides in the fact that the means for revolving the boxes or buckets at the predetermined periods and the device for releasing the keepers are located within the outer circumference of the rotary carrier, a highly compact arrangement thus resulting and the liability of interference with or derang'ement of such parts considerably reduced.

By employing' a construction such as that described the material can be delivered by the means direct to the hopper K ofthe packaging-machine K, which on account of the overhanging of the rotating box-carrier can be eompactl y disposed beneath the same.

l do not wish'to be understood as limiting' myself to the particular construction and a1'- rang'ement of parts shown and described, but reserve the right to such modifications as may be fairly considered within the scope of my invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In conveying' and delivering' means, the combination with a circular horizontally-rotating' carrier, of radially-disposed open-top buckets revolubly mounted in bearing's in the carrier, a radial series of vertically-vibratable keepers, having' their outer portions normally closely above the bucket-tops, and having' openings reg'istering' with those ofl the buckets, and provision for successively vibrating' said keepers and revolving the buckets pertaining' thereto, at one point of the carrier travel.

2. In conveying' and delivering' means, the combination with a circular horizontally-rotating' carrier, of' a series of radially-disposed open-top buckets revolubly mounted in bearings in the carrier, means tending' to counterbalance said buckets, a series of radial vertically-vibratable keepers having openings reg'- istering' with those of the buckets, said keepers normally retaining' the buckets against rotation, and provision for successively vibrating said keepers and revolving' the buckets pertaining' thereto, at one point of the carrier travel.

3. In conveying' and delivering' means, the combination with a rotatable carrier, of a box carried thereby, and a spring-supported trackway with which a portion of the box frictionally contacts to effect the discharg'e of' the box at one point of its travel.
